Application led June 4,

This invention relates to revolving display devices; and the principal object is to provide means for revolving a plurality of displaying members around a common center w1thout rotating them with relation to one another.

Another object is to provide a device such as described which may be driven by wind power, and which .will automatically shift its plane of revolution. n

A further object is the provision of means for producing novel illuminative effectss1- multaneousl'y with the rotation of the device'. v I

Other objects and advantages will appear in the course ofthe following description of the preferred form of this invention.

They support or casting l', consisting of a base piece 2' and a tube o-r hollow column projecting upwardly therefrom, pivot-ally supports the'oasting or supporting member 4, which has integral therewith a'depending hol-low shaft 5, journaled in bearings 6V at the upper and' lowerends in thetube 3. The' weigl-it of the block andthe parts carried thereby is borne on a ball-bearing 7 interposed between the upper endv of the tube 3 anda shoulder 8- formed integral with the A; horizontal stationary shaft 9 is' seeuredin a bore in the block 4l directly above the hol-low vertical shaft 5, and extends equal distancesfrom each side of the block.. Y

Adjacent each side ofthe block 4; are supr gears 10 onrnaled preferably on roller bearf, ings ll on` therstationary shaft 9. Housings 1925. Seria-l No.v $34,772.

12 are secured to the outer sides of the hubs of the gears lO preferably by means" of screws I3.k The outer ends of the' housings l2 are supported on the shaft 9 preferably by means of roller bearings l1, the nuts 14 on. the outer threaded ends of the shaft securing the gears, roller bearings and housings in position on the shaft. A

plurality of radially extending arms 15,

in the present instance four, preferably tubular in form,rv are screw-threaded innto the walls of each of the housings l2', irorining therewith a pair of oppositelyfacing rotary frames. Castings 16l are secured to the outer ends of the arms l5, and contain bearings 17 and lS'dispesed parallel and j perpendicular, respectively, `te the shaft 9. The bearings 18 are alin'ed with similar bearings 19/ extending through the wall of the` housings l2 in juxtaposition to the gears l0. Shafts 2O are journaled. in the bearings '18 and 19, and have ailixed therete bevel pinions and 22,abuttin-g the inner' end faresy ofthe bearings l8= and 19, respectively. lJinions 22 are in mesh with bevel gears 23,

aflixed on the stationary shaft 9v in their respective housings 12.'. Coll-ars 24,., aliixed to the outer ends of the shafts 20', prevent endwise dislocation of the' said shafts. Pinions 21 mesh with bevel gears 25,1allixed to theinner ends of spindles 26, j-ournaled in the bearings` 1'7 Pinions 2l and 22 are of the same size and' face in the same direction on their respective shafts; and gears 23 and 25 are of the same size andv face toward the shafts 20. This relative facing and arrangement of the pinions 2l and 22 and gears 23 and 25 and their respective .s

constitutes a parallel motion meclianism,

whereby, when housings l2, arms l5, and

their associated parts rotate, any line taken transversely through any of the spindles 26 will always remain parallel to a line taken in. the same direction through the' stationary shaft 9. y V f The outer ends ofthe spindles 26' are reduced in diameter to form shoulders 27,

.against which abut metal discs 28, which cooperate' with similar metal discs 28 on the outer end: of the reduced portions tosecnre glass discs 29 in fixed relationto thel spindles 26 when the nuts 30 are sere-wed against the outer discs 28. Rubber washers 31 are preferably interposed between` the glass plates 29 and' the metal discs,I 28 to 'insu-re intimate ycontact and even distribution of pressure on the glass discs. It will be observed that the aforesaid parallel motion mechanism is connected at one end'to the supporting member yor block 4, since the shaft 9 is secured thereto; and at the other end to the display means or members 29, since the shafts or spindles 26 are connected to the discs or display members29 by means of the nuts 30. This-invention of the parallel motion mechanism between the discs 29k and the supporting member 4 assures that the angular relation between the discs 29 and the block or supporting member 4 Awill be maintained constant at all times, no matter what the position ofthe rotating frames may be at any instant. Otherwise stated, the parallel. motion mechanism prevents r0- tation of the discs 29 on their axes with relation to the supporting lmember 4, but permits such rotation relatively to the ro-` tating frames, which comprise the housing 12, tubes `l5, and brackets 16. That this is true may be easily verified by studying the motions of the parts asthe .frame rotates.

' Assuming, for example, that the frame is rotating clockwise, so that the left hand discs are ascending while the right hand discs are descending, it will be observed that the' shafts 2() must rotate in a direction which may be stated to be clockwise if viewed from the" outer ends ofV the said shafts, by reason of theengagement of inner pinions 22, fixed on shafts 20, with stationary gears 23, fixed on stationary shaft 9. Shafts 20, through pinions 21 and gears 25,

, rotate spindles 26 in a direction which must be counter clockwise with relation to the already 4rotatimg frames, and, if the pinions 21 and 25 `bear the same speed relations to one another as do the pinions 22 and 23, it will be evident that the rotation of the frames is compensated for by the counterrotation of the discs, so that the discs remain relatively stationary on their axes with respect to the block 4. The glass discs 29 are one embodiment of diverse types of display members which may be aixed to the spindles 26. The display members may be of any suitable form to display advertisements or products of manufacture or other-commodities to the public. In the present instance, for the purpose of illustration, glass discs are Vemployed to exhibit to advantage various colors that maybe used in painting, varnishing, dyeing or coloring. In Figure 1, for example, thediscs are divided into four quadrants, one being colored blue 32, another red 33, another white 34, and another, say, yellow V35. The various colored quadrants are so disposed on the various discs that, as the` frame revolves, say, in a `clockwise direction, Aall the blues are in the inner quadrants. v As the rotation continues, the blues move outward and the' yellow quadrants become the inner ones.V

and immediately tracts the attention of the passerby.

This effect may be enhanced by illuminating, say, only the inner quadrants. Since the discs 29 are of glass, the light may .be Y

placed on the inner side of the frame and be transmitted through the glass to the observer. Theillummation may be produced by electriclamps 36, secured in sockets 37, and supplied with current through wiring 38, passing through conduits 39, formed in the block 4. y brushes 40, secured to insulating blocks 41,

The wiring 38 `terminates in attached to the inner side of the hollow shaft V5. Y The brushes 40 engage respectively the contact ring"42 and contact plug `43 imbedded in insulating plug 44 in the bottom oi' hollow column 3. Wiring 45 extends -from the ring 42 and plug 43 to asuitable source of electric current. This device may also be employed to project lights of varying colors on objects within its range.

Only one rotary frame may be used;` but preferably two are em loyed, each facing toward the outside oi) the device. The frames may be drivenin any suitable manner and from'any available source of power. It is preferred to drive thetwo frames simultaneously; and, where the device is set windpower may 4be employed up` outdoors, to rotate the frames. To this end, horizontallydisposed bearings 46 and 47 are4 formed in the block 4, vthe bearings 46 extending transversely of the block at the sides thereof beyond the gearsllO, and the bearings 47 being formed within a tubular extension 48 projecting outwardly from the block beyond the bearings 46 and at right angles thereto. A shaft 49 is ournaled in bearings 46, and has afiixed thereto spur pinions 50, which mesh `with the Vgears 10.

The block 4 lis recessed to provide room for mtermeshing bevel gears 51 and 52, respectively aiiixed to the shaft 49 and the inner end of a shaft 53 47. A wind-drivenrotary member, such as a propeller 54, is vatiixed to the outer endv of the shaft 53. An arm` 55 projects horizontally from the other and has secured to its outer end a vane 56, which functions to turn the block Von its pivotal support 1 to accommodate the propeller V54 to windsnwhich are continually shifting in direction. may be viewed from opposite sides of the device as the block rturns onitspivot.

Having thus fully described this invenjournaled in the bearings end of the block 4 Y The displaymatter i tion, I lhereby reserve the benefit of all V parting from the spirit of this invention or the scope of the following claims.

I claim: i

l. A device of the character described comprising a supporting member, a frame rotatably connected thereto, a plurality of display members rotatably carried by the frame and grouped around the axis thereof adjacent to each other and having similar character-bearing sections similarly arranged thereon, and a parallel-motion mechanism connecting said supporting member and said display members whereby the vertical and horizontal diameter of each display member l remains parallel With the same diameters of the other display members when said frame is rotated.

`2. A device of the character described comprising a supporting member, a rotatable r'rame carried thereby, a plurality of display members comprising similarly colored sections similarly arranged thereon, the said members being rotatably mounted on connecting said supporting member and said display members whereby the vertical and horizontal diameter of each display member remains parallel with the same diameters of the other display members when said frame is rotated, said colored sections being so dis-l posed on said display members that all the sections of the display members which are adjacent to the center of the frame are of the same color, and that during rotation of the frame the similarly colored sections that are adjacent to the center of the frame are replaced by sections that are similarly colored with relation to one another but are colored diiierently than the sections they have replaced.

In testimony whereof I hereunto affix my signature.
